Marie De Diabolus, a devoted chienne, prepares for her anniversary session with her master, Diabolus. She's an amateur at this, but her desire to please is evident. Dressed in black lace, she begins to touch herself, her fingers tracing her curves, igniting her senses. Diabolus enters, his presence commanding. He orders her to the floor, and she obeys, her eyes locked onto his. He unzips, and Marie eagerly takes his cock, her mouth working in rhythm with his thrusts. She's a good chienne, taking his length, her moans vibrating against his shaft. Diabolus' grip tightens, his thrusts becoming more aggressive. Marie's eyes water, but she never stops, never pulls back. Diabolus' climax is explosive, his cum filling Marie's mouth. She swallows, her eyes never leaving his, a silent promise of her eternal devotion.
